Research on compound controller in nuclear power plants

The reactor power control system is the core of the reactor control system in the nuclear power plant. Taking an experimental reactor as the research object, the compound control structure including the state feedback and the PID controller to control the nuclear reactor power are adopted. The existence of the state feedback array can obviously improve the dynamic characteristics of the power system, restraining the controlling quantity of the system effectively; PID controller plays the role of fine-tuning the system. The simulation results show that the method is correct and effective. (authors)
